Facts about Fluorescent Quantum Dots
- 05
Biological imaging applications of fluorescent quantum dots benefit from their size range of roughly 2 to 10 nanometers, comparable to many proteins and cellular structures.
- 04
Fluorescent quantum dots exhibit significantly greater photostability than traditional organic fluorescent dyes, resisting photobleaching far longer under continuous illumination.
- 03
The broad absorption spectrum of fluorescent quantum dots allows a single excitation light source to simultaneously excite dots of multiple sizes, enabling multiplexed imaging.
- 02
Cadmium selenide is one of the most widely studied materials used to produce fluorescent quantum dots due to its highly controllable optical properties.
- 01
Semiconductor fluorescent quantum dots emit light at wavelengths that are tunable by adjusting their physical size, with smaller dots emitting blue light and larger dots emitting red light.
